Roleplaying canon refers to the canon that will be established at the beginning of a roleplaying session. Game masters may choose to adhere to the default canon stated below, or resort to a fanon that they established themselves earlier.

Default canonEdit

Fallout 3Edit

  • The Brotherhood of Steel of the Capital Wasteland overcame the Enclave, nuking Raven Rock and the mobile base crawler in the process.
  • Project Purity was activated by the Lone Wanderer without the use of the Enclave's modified FEV.
  • The completion of side quests is largely irrelevant.
  • Add-on outcomes are up to the discretion of game masters.

Fallout: New VegasEdit

  • Robert House was victorious at the Second Battle of Hoover Dam, allying with all minor factions that Courier could convince to aid House in the battle (including the Boomers, the Enclave Remnants, the Followers of the Apocalypse and the Great Khans). The Brotherhood of Steel was in turn eliminated, as per House's instruction.
  • The New California Republic is pushed back into California; their jurisdiction ends at the Mojave Outpost. President Kimball's assassination is foiled and he lives to see the Second Battle of Hoover Dam.
  • Caesar's Legion withdraws back into the Four States Commonwealth (Utah, Colorado, New Mexico, and Arizona).
  • All those captured by Elijah in the Sierra Madre live; Christine stays and watches over the Madre, while Dean and God and Dog left.
  • The White Legs were crushed by a coalition of Dead Horses and Sorrows, led by Joshua Graham and the Courier.
  • The wondrous technology of the Big Empty remained in the Big Empty.
  • None of the Divide's nukes were launched; both the NCR and Legion remain intact. The Courier convinced Ulysses to stand down, and he became warden of the Divide.

User fanonsEdit

Other users have created their own canons which differs from the default canon. These include:


Did we miss something, let us know. Leave a suggestion below the line with a signature.

How did House win exactly? Tactics? Overwhelmed? Robots?

  • I think we should remove the New Vegas canon(seriously house? How the fuck does House win when he can't even lift his own fingers?)for now until Bethesda or Obsidian says something in Fallout 4(House winning? THAT DOESN't MAKE ANY FUCKING SENSE!!!!!! sorry) --Even tinyer This is my machine,There are many like it but this one is mine 23:34, February 24, 2016 (UTC)
